Abstract: A method for manufacturing a rotor blade component of a rotor blade includes feeding a flat sheet of material into a thermoforming system, wherein the material comprises at least one of a thermoplastic or thermoset material. The method also includes heating the flat sheet of material via the thermoforming system. Further, the method includes shaping the heated flat sheet of material via at least one roller of the thermoforming system into a desired curved shape. Moreover, the method includes dispensing the shaped sheet of material from the thermoforming system. In addition, the method includes cooling the shaped sheet of material to form the rotor blade component.

Abstract: The present disclosure is directed to a method of manufacturing a rotor blade for a wind turbine. The method includes providing a blade mold of the rotor blade. Another step includes placing an outer skin layer in the blade mold. The method also includes placing one or more structural inserts in the blade mold atop the outer skin layer as a function of a load of the rotor blade. Further, each of the structural inserts includes a plurality of cells arranged in a predetermined pattern. Further, the cells have varying cell sizes. The method also includes placing an inner skin layer atop the one or more structural inserts and securing the outer skin layer, the one or more structural inserts, and the inner skin layer together to form the rotor blade.

Abstract: The present disclosure is directed to a method for forming a fiber-reinforced polymer component. The method includes impregnating a first fiber tow with a polymerizable liquid contained within a reservoir to form a first impregnated fiber tow. The method also includes positioning the first impregnated fiber tow within a build region of the reservoir. The build region has a shape and size corresponding to a cross-sectional shape of the fiber-reinforced polymer component. Furthermore, the method includes irradiating the build region of the reservoir to form a polymerized solid from the polymerizable liquid within the build region. The polymerized solid encases a portion of the first fiber tow to form at least a portion of the fiber-reinforced polymer component.

Abstract: Wind turbine rotor blade components including pultruded rods and methods of manufacturing the same are disclosed. More specifically, the rotor blade component includes a plurality of pultruded rods housed within an enclosed primary outer casing. The enclosed primary outer casing includes a hollow interior, a root end, and an opposing tip. As such, each of the plurality of pultruded rods is received within the enclosed primary outer casing and secured therein via a first resin material. Further, an arrangement of the plurality of pultruded rods within the primary outer casing and a relationship of a maximum dimension of each of the plurality of pultruded rods and a maximum dimension of the enclosed primary outer casing are configured to maximize flexibility of the rotor blade component.
